Measuring Frequency

Never measure the frequency where the voltage or current level exceeds the

specified range. Manually set the voltage or current range if you want to
measure frequencies below 20 Hz.
Your multimeter allows simultaneous monitoring of real- time voltage or current
with frequency, duty cycle, or pulse width measurements.
